Learn How to Spot Mate in 3: Back Rank Mate
This puzzle is a classic tactical finish in a middlegame where active pieces outweigh static material. White’s queen and rook coordinate to exploit the enemy king’s limited escape squares, while the black back rank becomes the real target. The key idea is a forcing sequence that drags a defender away and then uses a rook to deliver the final blow. It is a strong example of tactical refutation, where a seemingly active defense collapses to a direct mating net.
